Application ed November 16, 19111.

To aZZ whom t may concern.'

Be it known that I, EMIL L. CLAUS, a citizen of the United States, residing at the city of Milwaukee, county of Milwaukee, and State of Visconsin, have invented new and useful improvements in Cocks, of which the following is a specification.

My invention relates to improvements in devices for regulating the size of the discharge orifice of gas or water cocks.

lThe object of my improvements is to provide means for regulating the size of the discharge orice of a gas or water cock by closing such orifice from two opposing sides only in such a manner that the flow of iiuid will not be retarded, but instead will be diecharged in a flat and unbroken stream.

My invention is explained by reference to the accompanying drawings in which Figure 1 represents a side view thereof.

Fig. 2 is a similar view to that shown in Fig. 1, drawn at right angles thereto.

Figs. 3 and 11 are longitudinal sections of the discharge end of the cock shown in Figs. 1 and 2, drawn at right angles to each other.

Fig. 5 is a transverse section, drawn on line zu, .r of Fig. 3.

Fig. 6 is a transverse section drawn on line 1 y of Fig. 4:.

Fig. 7 is a side view, part in section, of the discharge end of the cock,

Fig. 8 is a side view of the orifice closing member removed from the cock, and Fig. 9 represents a modified form of the discharge orice of the cock.

Like parts are identified by the same reference numerals throughout the several views.

1 represents the body of the cock, which is provided with an inlet branch 2, of ordinary construction. 3 is a plug for closing the passage of the gas through the body of the cock. 4 is the handle of the cock, which is connected with the plug 3 in the ordinary way. The plug 3 is retained in close contact with the body 1 by the screw 5, spiral spring 6 and washers 7 and 8 in the ordinary manner.

rlhe cock thus far described is substantially of ordinary construction. 9 represents the discharge orifice of the cock, which is preferably rectangular in shape, and the same is adapted to be closed by turning the cap 10 forward or toward the body of the cock on the threaded sleeve 11. The rectangular orifice 9 is closed as the cap 10 is Specification of Letters Patent.

turned toward the body of the cock by the converging ends 12, 12 of the member 13.

It will be understood that the member 13 bears at its inner end lil against the shoulders 15 of the body, and that said member 1.3 is adapted to be revolved with the cap l() as said cap is turned forward on its threaded bearings. lt therefore follows that as soon as the cap 10 is turned forward far enough to engage the converging ends 12 of the member 13, said member 13 will thereafter revolve with the cap. Since, however, the member 13 cannot move rearward with the cap the discharge orifice will be gradually closed as it is brought over the converging ends 12 of said member 13. The member 13 is adapted to closely fit the sides of the discharge orifice, whereby the gas or other fluid can only escape through the space 16 between said converging ends, and that as soon as such converging ends are brought together by contact with said cap the stream of gas or other fluid will be entirely cut off. The opposing surfaces of the converging ends, 12, 12 are preferably made flat and straight whereby the stream of fluid is flattened as it escapes from the cock. While owing to the fact that the converging members 12 are provided with two opposing converging surfaces 17, 17, the stream of fluid as it passes out through the space 16 is caused to converge as indicated by dotted lines in Figs. t and 7. To facilitate the proper adjustment of the cap 10 upon the threaded .sleeve 11, said sleeve is preferably provided with a stop nut 18, which may be turned forwardly or backwardly on said sleeve, whereby it is adapted to limit the forward movement of said cap as the discharge aperture is being closed. The connecting members 12, 12 are preferably yieldingly connected together at their inner ends by the member 19, and said members 12 are adapted to be thrown apart by the resilient action of the members 20, 20 while said members 20 yield sufiiciently to permit the converging ends 12 to come togetheras the cap 10 is turned forward on said-threaded sleeve.

By the modified form shown in Fig. 9 the discharge orifice 25 is made round instead of rectangular.

It will be understood that the cap 10 is pro vided upon two opposing sides with longitudinal grooves 21, 21 for the reception of the converging ends of said members 13,

of Ll whereby as the cap 10 is turned forward said ends will enter said grooves and thereby cause the members 13 to turn with said cap until said oriice is closed by said member 13.

As the cap l0 moves forward over the member 13 the converging ends of said member are forced toward each other by contact with said cap until said orice is entirely closed. a

The end 22 of the cap is preferably made slightly concave whereby the ends of the members 13, in case they should protrude slightly from the orifice, are shielded from contact.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is-

l. In a device of the described class, the combination with the discharge end of a coclr, of an adjustable cap having longitudinal angular grooves, an orifice closing member located in said cock and having slidable bearings in said grooves and having ends conforming in shape to and adapted to iit the discharge opening in said cap.

2. In a device of the described class, the combination with the discharge end of a cock, of an adjustable cap having a discharge orifice, and longitudinal angular grooves, an orifice closing member located in said cock, having slidable bearings in said grooves, the ends of said orifice closing member conforming in shape to and adapted to Close said discharge orifice.

In testimony whereof I aHiX my signature in the presence of two witnesses.
